Historical Thrillers are one my favorite genre's. It’s the best of both worlds. The characters were/are real people and reading about them brings history alive in a way that textbooks just can’t. The fiction bit allows the author some room for speculation. It’s fun to see each authors take on the same historical characters. I think this genre keeps the past in the present and encourages people to look back and learn. The Thriller bit digs into the reader, blows the dust off the past and rips a hole through time to keep the story fresh.
